- NASA-Funded Study Extends Period When Mars Could Have Supported Life
The 1907 book Is Mars Habitable? by British naturalist Alfred Russel Wallace was a reply to, and refutation of, Lowell's Mars and Its Canals. Wallace's book concluded that Mars "is not only uninhabited by intelligent beings such as Mr. Lowell postulates, but is absolutely uninhabitable."
29 paź 2024 · A new paper in Nature Communications makes their most compelling case to date that Mars’ life-enabling magnetic field could have survived until about 3.9 billion years ago, compared with previous estimates of 4.1 billion years — so hundreds of millions of years more recently.
2 lut 2022 · The late Noachian period (from 4.1 billion to 3.5 billion years ago) is the period usually thought to be habitable on Mars, with significant rain near the equator, as demonstrated by the presence of valley networks – features formed by erosion from flowing water — at this age.
4 sty 2023 · There’s lots of pieces of evidence that say there was once a huge ocean on Mars and an atmosphere that could have supported life. But there’s still a lot of Mars left to explore. There are places that are potentially habitable, like the deep subsurface.
28 lis 2023 · Robotic rover tools can reveal a lot about potential for habitability, but returning physical samples is absolutely critical for determining whether these rocks do contain evidence of life.
7 paź 2024 · NASA’s Curiosity rover, currently exploring Gale Crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life — with evidence for widespread liquid water on the surface — to a surface that is inhospitable to terrestrial life as we know it.
